JOSEPH R. .'BLAINE, OF CHICAGO, ILLINOIS, ASSIGNOR TO MIEHLE PRINTINGPRESS AND MANUFACTURING COMPANY, OF ILLINOIS.

CHICAGO, ILLINOIS, A CORPORATION 0F WATER FOUNTAIN.

Application filed August 24, 1921. Serial No. 494,993.

To all whomc't may concern.

Be it known that I, JOSEPH R. BLAINE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in later Fountains, ofwhich the following is a specification.

This invention relates to printing presses, and more particularly tomeans for damping the plate cylinder.

It is customary in certan types of printing presses to provide means forapplying a small quantity of water to the plates. This is accomplishedby use of rolls, one of which is mounted with its periphery in a watercontainer, another being mounted for oscillation between the watertake-up roll and one or more distributing rolls.

The object of this invention is to provide a simple and eiticientarrangement whereby the water may be conveyed to and properlydistributed upon the plates in a manner to meet the requirements forsuccessful coinmercial use. l

This and other objects are accomplished by means of the arrangementdisclosed on the accompanying sheet of drawing, in which the singlefigure is a fragmentary side elevation of a printing press embodying myinvention.

The invention is disclosed in connection with a printing press having aplate cylinder 10, to which ,water is conveyed from a suitablereceptacle 11, water being taken up from said receptacle by a take-'uproll 12. A ductor roll 13 mounted in an oscillating arm 14intermittently conveys the water from the take-up roll 12 to anintermediate roll 15, which is driven by a gear 16. Water is thentransferred from the intermediate roll 15 to a lower roll 17, whichconveys water directly to the plate cylinder 10. A second plate cylinderengaging roll 18 is provided which receives its supply of water from theirst plate cylinder engaging roll 17 through an intermediate roll 19driven by an intermediate gear 20.

It is seen, therefore, that the supply of water to the plate cylinder 10is divided at the roll 17, the larger amount of water being supplied tothe cylinder through the roll 17 and the remainder of the water beingsupplied to the cylinder 10 through an intermediate roll 19 and secondplate cylinder engaging roll 18. Although the second cylinder engagingroll 18 does convey some wate-r to the plate cylinder 10, its mainfunction .is to distribute water placed on the cyl* inder by thefirstroll 17. It also acts to re-v lieve the platek cylinder of any excess ofwater which may 'be supplied by the roll`17. By means of thisarrangement the plates on the cylinder 10 are properly provided withwater which is distributed and any excess of water absorbed in a mannerto meet all of the requirements for successful commercial use.

IVhile I have referred to roll 17 as the lower roll, I wish to make itclear that I refer particularly to the roll which iirst engages theplate regardless of the direction of rotation of the plate cylinder 10.

It is my intention to cover all modifications Vof the invention fallingwithin the spirit and scope of the following claims.

I claim:

1. In a printing press, the combination ot' a plate cylinder, a. waterreceptacle,.means for conveying water from said receptacle to Saidcylinder including a plurality of rolls engaging the cylinder and anintermediate roll, water being supplied to one of the cylinder engagingrolls and some water being supplied from said first cylinder engagingroll by said intermediate roll to another cylinder engaging roll wherebywater is supplied to and distributed on said cylinder, a

gear for driving one of said cylinder engaging rolls, and a separategear for driving the intermediate roll.

2. In a printing press, the combination of a printing cylinder, a watersupply, means for conveying water from said sup-ply to said cylinderincluding a plurality of rolls engaging the cylinder,all of the waterbeing supplied to one ofsaid cylinder engaging rolls, an intermediateroll out of engage ment with said cylinder for conveying some water fromsaid first cylinder engaging'roll to another cylinder engaging rollwhereby water is supplied to and distributed on the cylinder, a gear fordriving the cylinder engaging roll first receiving all the water, and aparate gear for driving the intermediate ro i Signed at Chicago,Illinois, this 12th day of August, 1921.
